What are bedbugs in chickens? - briefly

Bedbugs infesting poultry are Cimex lectularius, small hematophagous insects that feed on chicken blood, leading to skin irritation, anemia, and decreased egg production. Infestations thrive in warm, crowded housing and are managed with chemical treatments, thorough sanitation, and environmental controls.

What are bedbugs in chickens? - in detail

Bedbugs that infest poultry are small, nocturnal, hematophagous insects belonging to the family Cimicidae. Adults measure 4–5 mm, have a flattened, oval body, and lack wings. Their coloration ranges from reddish‑brown to dark brown, becoming paler after feeding. Antennae are short, and the mouthparts are adapted for piercing skin and sucking blood.

The life cycle comprises five nymphal stages and a mature adult. Each stage requires a blood meal to molt, and development can be completed in 2–4 weeks under warm, humid conditions. Females lay 1–5 eggs per day, depositing them in crevices, nesting material, or equipment. Eggs hatch in 5–10 days, and the emerging nymphs resemble adults but lack fully developed mouthparts.

Infestations manifest as:

• Small, dark specks on the bird’s skin, especially around the vent, thighs, and under wings.
• Irritation, restlessness, and increased preening behavior.
• Small, dark fecal spots on feathers, perches, or coop surfaces.
• Anemia in severe cases, detectable by pale combs and reduced vigor.

Diagnosis relies on visual inspection of the bird and the environment. Sticky traps placed near roosts can confirm activity. Microscopic examination of collected specimens distinguishes bedbugs from mites and lice by the characteristic beak‑like rostrum and the absence of legs on the ventral surface.

Control strategies include:

  1. Thorough cleaning of the coop, removal of all organic debris, and replacement of bedding material.
  2. Application of approved insecticides, such as pyrethroid‑based sprays, following label instructions and observing withdrawal periods for meat and eggs.
  3. Use of diatomaceous earth in cracks and crevices to desiccate insects.
  4. Installation of physical barriers—screened vents, sealed cracks, and smooth surfaces—to limit harborage sites.
  5. Regular monitoring with sticky traps and periodic inspections to detect resurgence early.

Preventive measures focus on biosecurity: quarantine new birds, disinfect equipment before introduction, and maintain low humidity levels (below 60 %) to inhibit development. Heat treatment of equipment (≥ 50 °C for 30 minutes) or freezing (≤ −20 °C for 48 hours) eliminates all life stages.

Bedbugs do not transmit diseases to humans, but heavy infestations can compromise poultry health, leading to reduced weight gain and lower egg production. Prompt identification and integrated pest‑management practices are essential to protect flock welfare and productivity.
